length of the UDP header itself, so subtract the length of the header
when using it to limit the length of the payload tvbuff.
Clean up the computing of the captured length of the payload tvbuff (we
really should get rid of the "length" argument to "tvb_new_subset()",
and have it compute the captured length based on the supplied reported
length and the amount of that data actually present in the parent
tvbuff).
Don't fetch the length and checksum fields until we use them (so that we
don't throw an exception until then, and fail to process the source and
destination ports), and check whether the length is bogus regardless of
whether we're building a protocol tree or not.

If we get such an error, always call "file_error()" to get an indication
of what the error was and, if it returns 0, set the error to
WTAP_ERR_SHORT_READ.

should be the length of the packet being dissected, so that if we throw
an exception dissecting it, the item covers the entire packet (because
it's incomplete, and thus *all* of it is the beginning of the header).
Instead, we should pass the length of the part of the header prior to
the protocol field as an argument to "dissect_ppp_common()", and it
should use that to set the length of that item.

that return the next packet from a set of {chronologically sorted,
sequential-by-file} packets; it doesn't need to have a loop over all
those packets, or any code to write packets.
Supply those abstractions, change the code that merges packets to do its
own writing, and have the Ethereal version manage a progress bar and
have the mergecap version print packet numbers in verbose mode, as the
common merge code used to do.

The offset is relative to the first byte of the TIFF structure, which is
after the "Exif\0" *and* the extra byte after "Exif\0".
Loop over all IFDs.
Sanity check the offset to the first IFD and the offset in each IFD to
the next IFD.

Have "merge_open_outfile()" do all the work of filling in the
merge_out_file_t structure, with the values to use passed as arguments.
Get rid of some structure members that used to be used solely to pass
information to "merge_open_outfile()".
Add a "cf_merge_files()" routine to do the merging and reporting of errors.

Clean up indentation.
If we dissect an octet string and then re-dissect it as a particular
